In doing some website research and SEO research, I came across a couple of sites that have the following <meta> in their source code:
<meta name=”robots” content=”NOODP, NOYDIR” />
In a recent article, I wrote about how to set up your meta data for your site but I didn’t discuss the ‘robot’ meta tags. Basically this <meta> tag tells the “internet robots” what to do with your site, like FOLLOW, NOINDEX, INDEX, NOFOLLOW.
These tags go in-between your <head> & </head> tags.
So what are NOODP & NOYDIR ?
NOODP: If someone searches for a specific keyword, Google may use descriptions from the open directory project as the page title and meta description. With this tag, you have the option to opt-out of what the DMOZ uses for your site title and description. So if you have a site listed on DMOZ, the listing information can be outdated, inaccurate and maybe not written very well. So in the long run, this may affect your SEO and site rankings.
NOYDIR: Similar to the above NOODP, this tag prevents the search engines from displaying your Yahoo! Directory page title and meta description.
